Cheched tires and alignment. Inspected everything that could be checked ... nothing. I took the moterhome to an RV repair shop and they found a broken /corroded support bracket/brace between the chassis and the lower support member of the dashboard. Poor materials selection and poor design of the structure supporting the dashboard. There are 2 support brackets; 1 on passenger side and one on drivers side ..try inspecting these brackets for corrosion and/or broken welds. My steering column actually has slight movement and the seat of the pants feels like the drivers seat has slight movement.Re: Changing all exterior lightsHeadlight units are often OEM from a major auto/truck manufacturer; my 2000 Bounder used a Ford Bronco/pick-up truck headlight/turn signal unit. These may be available on the cheap from places like Auto Parts Warehouse. Just need to identify which headlight unit was used on your particular motorhome.Re: Banging Noise from Front of F-550 chassis ?Had similar issue with a 2000 Fleetwood Bounder; F-53 Chassis. Went through the whole front end diagnosis; found nothing. Turned out to be a rusted mount support between the motorhome and the chassis. There are two mounts; poor material selection by Fleetwood; both were rusted through allowing movement of the dashboard and driver's/passenger's seat. Scheduled repair @ Decateur, Indiana facility in Nov 2013. Repair couldn't be completed and am scheduled to go back in June 2014. Will require structural repair and bracing of dashboard and fabrication of support bract attaching chassis to coach body. There is a driver's/passenger's side support that you need to inspect for damage.
